Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a sill, a head opposite the sill, a first jamb, and a second jamb opposite the first jamb forming a window cavity therebetween, the sill including a lower surface and an upper surface and one or more compartments therebetween; and a weep hood arranged in the sill and configured to allow water and air to exit the one or more compartments within the sill.
Claims16
A fenestration unit comprising:
- a sill, a head opposite the sill, a first jamb, and a second jamb opposite the first jamb forming a window cavity therebetween, the sill including a lower surface and an upper surface and one or more compartments therebetween, and the sill including at least one side wall having an opening extending therethrough and the at least one side wall separates the one or more compartments within the sill from an exterior or interior side of the sill;
- and
- a weep hood arranged within the at least one sidewall and contacting the lower surface of the sill, the weep hood including one or more air vents and one or more water vents, the weep hood arranged within the opening of the at least one side wall of the sill such that at least a portion of the weep hood projects outwardly from the sill, and the weep hood configured to simultaneously allow water to exit the one or more compartments within the sill through the one or more water vents and allow air to enter the one or more compartments within the sill through the one or more air vents, wherein the weep hood includes a first portion configured to reside within the one or more compartments and a second portion configured to reside outside the one or more compartments, and the first portion of the weep hood includes the one or more water vents including an inlet extending parallel to at least a portion of the lower surface of the sill, and the first portion includes an inlet of the one or more air vents extending substantially perpendicular to at least a portion of the lower surface of the sill.
A fenestration unit comprising:
- a sill, a head opposite the sill, a first jamb, and a second jamb opposite the first jamb forming a window cavity therebetween, the sill including a lower surface and an upper surface and one or more compartments therebetween;
- and
- a weep hood arranged in the sill and including one or more water vents having one or more inlets arranged within the one or more compartments and parallel to the lower surface of the window cavity being configured to allow water to exit the one or more compartments within the sill and one or more outlets defining an external feature directly exposed to an exterior environment, and one or more air vents having one or more inlets perpendicular to the lower surface of the window cavity being configured to allow air to exit the one or more compartments within the sill;
- and
- wherein an upper boundary of the one or more inlets of the one or more water vents is defined by a first vertical height and an upper boundary of the one or more inlets of the one or more air vents is defined by a second vertical height, the first vertical height being less than the second vertical height.
